The clamping seat body 131 is movably connected with the bracket 110, and the clamping jaw 133 is movably connected with the clamping seat body 131 and surrounds a through hole. The reset element 132 is in reset fit with the clamping jaw 133, and is used for penetrating the traction rope 200 through the hole. Under the resetting action of the resetting piece 132, the clamping seat body 131 and the clamping jaw 133 are used for being in interference fit with the traction rope 200.
Above-mentioned transmission line high altitude auxiliary rope device 100, in the course of the work, unmanned aerial vehicle is connected with the one end of haulage rope 200, then, when needing to carry haulage rope 200 to high altitude construction district delivery tool and equipment, to operate unmanned aerial vehicle and fly to high altitude wire, unmanned aerial vehicle flight in-process, rope reel body 120 rotates and expands the insulating rope, owing to holder body 131 contradicts with clamping jaw 133 and haulage rope 200, can provide the resistance for haulage rope 200, avoid unmanned aerial vehicle traction speed too fast to lead to the pulling inertia of haulage rope 200 too big so that take out a large amount of haulage ropes 200 and lead to scattering even deviate from the rope reel, be favorable to improving the reliability of expanding of haulage rope 200. When retrieving haulage rope 200, clamping jaw 133 and the holder on the rope guiding mechanism 130 can play the supporting role to haulage rope 200, and rope guiding mechanism 130 and haulage rope 200 of rope reel portion remain to have certain pulling force throughout, just so can guarantee when rope reel body 120 rotates, haulage rope 200 rotates the recovery with rope reel body 120 in step throughout, avoid haulage rope 200 to loosen on rope reel body 120, appear the hank winding phenomenon to be favorable to avoiding retrieving haulage rope 200 and knotting the winding each other, improve haulage rope 200's recovery efficiency, and then be favorable to improving transmission line overhead work's work efficiency.
It should be noted that, under the restoring action of the restoring member 132, the holder body 131 and the clamping jaw 133 are used to be in interference fit with the traction rope 200, and it should be understood that, when the traction rope 200 does not pass through the passing hole, the diameter of the passing hole is smaller than that of the traction rope 200. During the operating condition, haulage rope 200 passes through the through hole for holder body 131 and clamping jaw 133 separate, reset piece 132 can play the reset effect to clamping jaw 133, makes clamping jaw 133 have the pressure of contradicting towards haulage rope 200, and then makes holder body 131 and clamping jaw 133 conflict cooperation, increases the frictional force of haulage rope 200 in the through hole.
Alternatively, the reset element 132 may be a sensor, spring, magnet, or other element having a reset function.
Specifically, referring to fig. 1, the reset element 132 is a spring. The clamping jaw 133 is elastically engaged with the holder body 131 by a spring. Through the elastic deformation of the spring, the clamping jaw 133 can continuously abut against the traction rope 200, so that the friction force is increased. The present embodiment provides only a specific choice of the reset element 132, but is not limited thereto.
In one embodiment, the end of the passage hole remote from the rope reel body 120 is provided with a tapered portion, the diameter of which gradually increases from the end near the rope reel body 120 to the end of the passage hole. Thus, when the traction rope 200 swings, the tapered portion can increase the swinging space of the traction rope 200, thereby improving the smoothness of the traction rope 200 when being wound and unwound, and avoiding abrasion of the traction rope 200 and the rope guiding mechanism 130.
In one embodiment, the wall of the through-hole is provided with a friction layer (not shown in the figures) for increasing the friction between the wall of the through-hole and the traction rope 200. For example, the friction layer is a sanding layer, resilient protrusions, a layer of rubber material, a layer of plastic material, or other friction-increasing structures and materials. In this way, the friction force between the clamping jaw 133 and the clamping seat body 131 and the traction rope 200 is further improved, and the guiding traction effect of the rope guiding mechanism 130 on the traction rope 200 is improved.
In one embodiment, referring to fig. 1, fig. 2 and fig. 3, the cord guiding mechanism 130 further includes a connecting seat 134. The connecting base 134 is provided with a sliding groove 135, and the clamping base body 131 is slidably connected with the connecting base 134. The holder body 131 is movable along the length direction of the connection holder 134, and the traction rope 200 wound on the rope reel body 120 passes through the sliding groove 135 and the passing hole for connection with the unmanned aerial vehicle. In this way, the holder body 131 can move along the sliding groove 135 on the connecting seat 134, and the position of the rope can be changed in the rope winding and unwinding process of the rope reel body 120, so that the traction rope 200 on the rope reel body 120 is wound more uniformly. On the other hand, the traction rope 200 passes through the sliding groove 135 and the through hole, so that the traction rope 200 is prevented from falling off from the rope reel body 120 and the bracket 110, and meanwhile, the traction rope 200 is supported, so that the winding and unwinding stability and reliability of the rope reel body 120 on the traction rope 200 are improved, and the traction rope 200 is prevented from scattering and intertwining on the rope reel body 120.
For further understanding and description of the longitudinal direction of the connecting base 134, taking fig. 1 as an example, the longitudinal direction of the connecting base 134 is indicated by any arrow on the straight line S 1 in fig. 1.
Alternatively, the shape of the chute 135 may be rectangular, arcuate, curved, or other irregular shape.
Specifically, referring to fig. 2 and 3, the sliding groove 135 extends along the length direction of the connecting seat 134, and the length direction of the connecting seat 134 is parallel to the length direction of the rope reel body 120. So, when rope reel is put the rope, holder body 131 can follow unmanned aerial vehicle's traction direction motion, can also follow the rope position motion of putting on the rope reel body 120, is favorable to improving rope efficiency, avoids blocking. When the rope is wound, the winding position can be adjusted at any time, so that the traction rope 200 is uniformly wound on the rope disc body 120, and the subsequent use is convenient.

In this way, the convenience of movement of the holder body 131 on the connection base 134 can be improved, and further the work efficiency can be improved when the rope reel body 120 is wound and unwound.
The length direction of the sliding groove 135 and the length direction of the connecting seat 134 are both directions indicated by any arrow on the straight line S 1 in fig. 2.
In one embodiment, referring to fig. 1,2, 3 and 4, the number of rope reel bodies 120 is at least two. The two rope reel bodies 120 are arranged on the bracket 110 at intervals, the rope guiding mechanism 130 is arranged between the two rope reel bodies 120, and at least two rope reel bodies 120 are used for winding the traction rope 200. Specifically, referring to fig. 1,2, 3 and 4, the number of rope reel bodies 120 is two. In this way, the volume and the mass of the single rope reel body 120 can be reduced, the winding quality of the single rope reel body 120 can be reduced, and the service life of the rope reel body 120 can be prolonged. The two rope reel bodies 120 are beneficial to winding longer hauling ropes 200, can be simultaneously used by two groups of hauling ropes 200, and are beneficial to improving the functions of the power transmission line high-altitude auxiliary rope paying-off device 100. The rope guiding mechanism 130 is arranged between the two rope reel bodies 120, so that the working stability is improved, meanwhile, two groups of traction ropes 200 can be conveniently and simultaneously wound and unwound, and the use convenience of the high-altitude auxiliary rope unwinding device 100 of the power transmission line is improved.
In one embodiment, referring to fig. 1, 2,3 and 4, the power transmission line overhead auxiliary rope paying-off device 100 further includes a speed control mechanism 140.
